• Using Tool (A), install piston with the front mark on the piston
head facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an inte rference of the connecting rod
big end.
22. Install connecting rod cap. • Match the stamped cylinder number marks (C) on connectingrod with those on connecting rod cap to install.
23. Tighten connecting rod bolt with the following procedure: CAUTION:
• Make sure that there is no gap in the thrust surface (A) of
the joint between connecting rod (1) and connecting rod
bearing cap (2) and that th ese parts are in the correct
position. And then, tighten the connecting rod bolts.
• If the connecting rod bolts are reused, measure the outer
diameter. Refer to EM-219, "
Inspection After Disassem-
bly".
a. Apply new engine oil to the threads and seats of connecting rod bolts.
b. Tighten connecting rod bolts in two steps using Tool.
• After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.
• Check the connecting rod side clearance. Refer to EM-219, "
Inspection After Disassembly".
24. Install oil pan (upper). Refer to EM-144
.
NOTE:
Install the rear oil seal after installing the oil pan (upper).
25. Install rear oil seal. Refer to EM-144

How to Select Piston and Bearing
INFOID:0000000005931034
DESCRIPTION
• The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
• For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
• For details of the measurement method of each part, the reuse standar ds and the selection method of the
selective fitting parts, follow the applicable procedures.
HOW TO SELECT PISTON
When New Cylinder Block is Used
• Check the cylinder bore grade on rear left side of cylinder block (L), and select piston of the same grade.
• If there is a correction stamp mark on the cylinder block, use it as a
correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to EM-219, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measur ement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
Selection points Selection parts Selection itemsSelection methods
Between cylinder block and
crankshaft Main bearing
Main bearing grade (bearing
thickness) Determined by match of cylin-
der block bearing housing

ing) and crankshaft journal

INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets and seal bear
ings with new ones when installing.
• Before installing a new heated oxygen sensor, clean and apply anti-seize lubricant to exhaust sys-
tem threads using suitable tool.
• Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a co ncrete floor; install a new one.
• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,
resulting in the MIL coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
• Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each part
for unusual interference, and then tighten them to the specified torque.
• When installing each mounting rubb er, avoid twisting or unusual extension in up/down and right/left
directions.

the direction shown.
• Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4). • Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
• Make sure the spring (3) sits properly on the flange surface by aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
• Center muffler (5)

INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
• Check to ensure that brackets and mounting rubber s are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration. Oxygen sensor thread cleaner : — (J-43897-18)

Checking Fuel LineINFOID:0000000005931055
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loos
e connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000005931056
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work area.
• Put drained fuel in an explosion-proof containe r and put the lid on securely. Keep the container in
safe area.
CAUTION:
• Use gasoline required by the regulations for octane number. Refer to GI-4, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
• Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines. Refer to EC-499, "
Inspection" (HR16DE), EC-582, "Fuel
Pressure Check" (MR18DE).
- Disconnect the battery ground cable.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist tubes when they are being installed.
• Perform work on level surface.
• Do not tighten hose clamps excessi vely to avoid damaging hoses.
• After connecting fuel tube quick connector s, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
• After installing tubes, make sure there is no fu el leakage at connections in the following steps.
- Apply fuel pressure to fuel lin es by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
- Start engine and rev it up and check for fuel leaks at connections.
• Use only a genuine NISSAN fuel filler cap as a replacemen t. If an incorrect fuel filler cap is used, the
MIL may come on.
• For servicing “Evaporative Emission System” parts, refer to EC-501, "
Inspection" (HR16DE), EC-528,
"Component Inspection" (MR18DE).
• For servicing "On Board Refueling Vapo r Recovery (ORVR)" parts, refer to EC-535, "
Component
Inspection".
